1. Transformer can step up or step down the voltage or current in an A.C. circuit.
2. It can be used to prevent D.C. from passing from one circuit to the other.
3. It can isolates two circuit electrically.
4. It can increase or decrease the v...alue of capacitor, inductor or resistance in an A.C. circuit.
